We put down the box and Sally relaxed on the box before we even opened it, watched me put it together, and has been enjoying it every day since!  It is a great color and matches my decor, something different than all of the tans and browns (colors I do not like) that are prevalent in cat towers.  Nice soft material, and a cinch to put together.    Even arrived in less than a week.  Cat has no problem getting onto any of the levels, put together as designed, and uses the tower for scratching and hopefully not the couch any more.

Pros: Easy to put together, cat loves it.  Great price that cannot be beat.
Cons: None!
